Simply put, Social Marketing, is online marketing through Social Networking websites.
Social networking is defined as the grouping of individuals together into to specific groups, often like a small community or a neighborhood. Although social networking is possible in person, especially in schools or in the workplace, it is most popular online. This is because unlike most high schools, colleges, or workplaces, the internet is filled with millions, if not more, of individuals who are looking to meet other internet users and develop friendships. When it comes to social networking online, networking websites are used.
Social networking websites are, in a way, like an online community of internet users with a common interest or goal such as hobbies, religion, or politics. Once you are granted access to a social networking website you can begin to socialize with other members of the social network. This socialization may include reading the profiles or profile pages of other members or even contacting them.
